A software system was designed whose aim is to support everyday scientific research of physicians in different fields of medicine. DREAM is a shell-like tool which can be customized embedding in it the desirable structure of a particular medical problem. Various basic statistical analyses are provided along with the decision support capabilities. The decision aid is proposed in two steps--feature selection and classifier design. Genetic algorithm is implemented as the feature selection procedure. The classifier design option includes crisp and fuzzy k-Nearest Neighbors rule and a two-level classification scheme based on majority rule on the votes of several first-level k-Nearest Neighbors classifiers. The system's performance is illustrated with a database from aviation medicine.
设计了一个软件系统,其目的是支持不同医学领域医生的日常科研工作。DREAM是一个类似外壳的工具,可以通过嵌入特定医学问题的理想结构进行定制。它提供了各种基本统计分析以及决策支持功能。决策辅助分两步提出——特征选择和分类器设计。遗传算法被用作特征选择程序。分类器设计选项包括清晰和模糊的k近邻规则以及基于几个一级k近邻分类器投票的多数规则的两级分类方案。通过航空医学数据库展示了该系统的性能。
